TECHNICAL FIELD
[0001] The present application relates to the technical field of grain screening, in particular to a grain screening device. BACKGROUND
[0002] The grain bar is a sheet-shaped or rod-shaped instant food made of oat, barley, highland barley, corn and other grains as raw materials, supplemented by nut kernels, dried fruits and other ingredients, and bonded by high-viscosity syrup. The grain meal replacement bar occupies a stable and increasingly mature market due to its excellent characteristics such as nutritional health, convenience and instant eating. In the production process of the grain bar, screening is one of the important links to ensure the quality of the grain bar. Most of the existing screening devices need manual assistance for discharging after screening the grains according to their different particle sizes. If there are too many screening discs, each screening disc needs to be discharged separately, which not only wastes time and effort, but also affects the production efficiency of the grain bar. CONTENT OF THE UTILITY MODEL
[0003] In order to solve the above-mentioned problems of the prior art, the present application provides a grain screening device which not only facilitates the discharging after screening, but also realizes the simultaneous discharging of multiple screening discs, has a simple structure, is easy to operate, saves time and effort, and effectively improves the work efficiency.
[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technology:
[0005] A grain screening device comprises a screening chamber, which is hollow inside and has a feeding port communicated with the top;
[0006] A plurality of screening discs are arranged in the screening chamber along the height direction, the mesh diameters of the screening discs decrease from high to low in sequence, the screening discs are rotationally connected to both ends of the inner wall of the screening chamber and the rotation shafts are arranged in the middle of the screening discs, and a sliding rod is arranged on one side of each screening disc, and the axis of the sliding rod is parallel to the axis of the rotation shaft of the screening disc;
[0007] A guide plate is movably arranged in the screening chamber along the height direction, a plurality of transverse grooves are arranged on the guide plate along the height direction and penetrate through the guide plate, and each sliding rod is slidably fitted in the corresponding transverse groove;
[0008] One side of each screening disc is open, and a baffle is movably arranged at the opening along a direction parallel to the axis of the mesh, and the baffle is used to open or close the opening of one side of the screening disc;
[0009] One side of the screening chamber is provided with a discharging chamber, a plurality of placement grooves are arranged in the discharging chamber along the height direction and penetrate through the discharging chamber, and a discharging disc is movably arranged in each placement groove, each discharging disc is arranged below the corresponding screening disc, and the discharging disc is used to abut against the opening of the screening disc and realize the discharging of the screening disc when the screening disc is tilted.
[0010] The beneficial effects of this invention are as follows: by switching the movement mode of the guide rod in the vertical direction, it is possible to switch between two states: shaking screening and tilted discharge. When the guide plate makes a small reciprocating motion in the vertical direction, multiple screens shake simultaneously, allowing for screening of grains according to their particle size. When the guide plate moves downward in the vertical direction, multiple screens tilt simultaneously until they align with the discharge plate. Opening the baffle allows for simultaneous discharge of grains of different sizes. Finally, the movement of the discharge plate transfers the grains. This screening method not only facilitates the discharge of screened materials but also enables simultaneous discharge from multiple screens. It has a simple structure, is easy to operate, saves time and labor, and effectively improves work efficiency. Attached Figure Description

After waiting for a period of time, when the screening is completed, the guide plate 4 is moved downward, so that the plurality of sieve plates 3 are all rotated by a predetermined angle, when the bottoms of the sieve plates 3 are all attached to the bottoms of the corresponding discharge plates 6, the butt joint of the sieve plates 3 and the discharge plates 6 is realized, at this time, the sieve plates 3 are in an inclined downward state, the baffle 32 is opened, and due to the gravity, the grains on the sieve plates 3 will gradually fall from the sieve plates 3 to the discharge plates 6.
